In our previous study, we have demonstrated that peak inspiratory pressure over birth weight (PIP/kg) and mean airway pressure over birth weight (MAP/kg) were more significant risk factors for the development of neonatal chronic lung disease (CLD) than PIP and MAP. We aimed to develop a scoring method using the modified respiratory variables (SMUMRV) to predict CLD at early postnatal period. From 1997 to 1999, a retrospective review was performed for 197 infants <1,500 g for the development of t

We present two rare cases of anomalous vertebral artery (VA) with retroesophageal right subclavian artery. One patient had a right VA arising from the right common carotid artery (CCA), and a left VA originating from the third branch off the aorta. Both VAs ascended anteriorly to the transverse foramen of C5 to C6 vertebra and entered the transverse foramen of C4. The other patient had a right VA arising from the right CCA and entering the transverse foramen of C5. The presence of anomalous vari

It appeared that acquisition of in vivo 1H-NMR signals was possible in human spinal mass lesions on a 1.5 T clinical MRI unit. Detection of choline only in the spinal tumors may indicate that there is some potential in using in vivo 1H-MRS to distinguish spinal tumors from disc herniation mimicking spinal cord tumors, non-multiple sclerosis myelitis, and dermoid cysts. On the basis of our NMR findings, however, it was not possible to distinguish between benign diseases.

When approaching the BX via the pterion route, the appropriate surgical step and window should be selected according to characteristics of the PCoA and height of the BX.

Variceal bleeding was still the major cause of upper GI bleedings and did not decrease in prevalence over the 10-year period in Gangwon province, South Korea. However, the mortality rate of variceal bleeding decreased significantly.

Objective The extent of the far-lateral approach (FLA) has not yet been quantified for the region of the vertebral and posterior inferior cerebellar arteries (VA-PICA). We quantitatively analyzed six main sequential steps of the FLA. Methods A modified small FLA (msFLA) and a classic large FLA (clFLA) were performed sequentially on both sides of five cadaveric heads. A frameless navigational system was used to quantify the angle of attack for the origin (T1) and lateral medullary segment (T2) of

The levels of inflammatory mediators in GF of a premature newborn immediately after birth are strongly associated with those in AF of the newborn's mother.

TONIC SMOOTH MUSCLE EXHIBIT THE LATCH PHENOMENON: high force at low myosin regulatory light chains (MRLC) phosphorylation, shortening velocity (Vo), and energy consumption. However, the kinetics of MRLC phosphorylation and cellular activation in phasic smooth muscle are unknown. The present study was to determine whether Ca(2+)-stimulated MRLC phosphorylation could suffice to explain the agonist- or high K(+)-induced contraction in a fast, phasic smooth muscle. We measured myoplasmic [Ca(2+)], M
